Detailed ways

In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the embodiments of the present disclosure will be further described in detail below through specific implementation manners in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present disclosure, not to limit the present disclosure.

In the process of using a mobile phone, when the head or hands of the human body are close to the mobile phone, the head and hands, which exist as lossy conductive media, will have a significant impact on the radiation characteristics of the mobile phone antenna, which can be specifically reflected in the absorption caused by the human body For problems such as the decrease of total radiated power and the mismatch of antenna feed ports, the longer the wavelength, the greater the impact, and the impact of low frequency is higher than that of medium and high frequency. In the related technology, during the communication process of the mobile phone, the current distribution of the bottom plate of the mobile phone in the low frequency band is its main source of radiation. Therefore, it is difficult to change the main radiation direction and zero point position of the pattern. The greater the gain of the antenna in the direction of the hand, the greater the loss. The gain of the loss will directly affect the human body. In the long run, it may significantly affect the health of the human body, making the user's call experience poor.

Embodiment one

In order to improve the problem in the related art that the communication performance is degraded and the user experience is deteriorated due to the holding of the antenna on the communication terminal, this embodiment provides a communication terminal. Please refer to FIG. 1 and FIG. 2, the communication terminal includes: a first antenna 1, used to send and receive communication signals; a second antenna 2, used to generate a first coupled signal, and the first coupled signal is used to superimpose the communication signal; at least A sensing module 3 is used to detect the environmental information within the preset range of the first antenna 1; a signal processing module 4 is used to obtain the first antenna 1 when the detection result of the environmental information includes that the first antenna 1 is at least partially blocked by the human body The communication signal is sent to the main processing module 5; the main processing module 5 is used to control the second antenna 2 to generate a first coupling signal corresponding to the communication signal of the first antenna 1 according to the communication signal of the first antenna 1; and The adjustment module 6 is configured to adjust the first coupling signal of the second antenna 2, so that the superposition of the communication signal and the first coupling signal reduces the radiation gain towards the direction of the human body.

The communication communication terminals in the embodiments of the present disclosure include devices with mobile communication functions such as mobile phones and tablet computers; these devices are often equipped with at least one set of antennas at corresponding positions on the housing for sending and receiving communication signals to achieve wireless communication . As for the installation position of the antenna, taking a mobile phone as an example, the installation method is along the frame of the mobile phone, and is arranged at the bottom and/or top of the mobile phone. Among them, in the embodiment of the present disclosure, the antenna installed on the communication terminal is the first antenna 1, and the first antenna 1 represents the existing communication antenna of the communication terminal, and there is no specific limitation on the location and quantity of these antennas , but its usual location will be set on the side of the communication terminal. Please refer to FIG. 1 , which shows a typical installation position of the first antenna 1 , where the structure of the first antenna 1 includes corresponding feed sources and radiators.

In order to compensate for the communication of the first antenna 1 , mainly to improve the communication quality when the first antenna 1 is blocked, the embodiment of the present disclosure further includes a second antenna 2 . The second antenna 2 is also arranged on the communication terminal, and its function is to generate the first coupling signal, and the purpose of generating the first coupling signal is to superimpose with the communication signal, especially to make the result of the superposition of the two reduce the direction of the human body. The radiation gain of the antenna can reduce the influence of the radiation of the antenna on the human body, reduce the radiation loss of the antenna, and improve the communication quality.

In order to achieve the above purpose, the structure of the communication terminal in the embodiment of the present disclosure further includes at least one sensing module 3 . The purpose of the sensing module 3 is to detect the environmental information within a certain range of the first antenna 1 , that is, to detect the occlusion around the first antenna 1 , usually the sensing module 3 can be realized by a distance sensor. The number of sensing modules 3 can be multiple, and these sensing modules 3 can be set around the first antenna 1, so that once the user blocks the first antenna 1 by holding it, or the user blocks the first antenna 1 by approaching the head The first antenna 1 can detect the fact that the first antenna 1 is blocked through the sensing module 3 .

The setting method of the induction module 3 can be set according to the characteristics of the first antenna 1; for example, if the first antenna 1 is an antenna arranged at the bottom of the communication terminal, since the communication terminal is usually held by hand when in use, If the first antenna 1 is shielded, then the sensing module 3 can be arranged on both sides of the communication terminal; , to block the first antenna 1, then the sensing module 3 can be arranged on the surface near one side of the user's head. In other words, the purpose of setting the sensing module 3 in the embodiment of the present disclosure is to detect the occlusion of the first antenna 1 , as long as the first antenna 1 is set at a reasonable position.

On the premise that the sensing module 3 is set, if the first antenna 1 is blocked, it will be detected by the sensing module 3; The first antenna 1 and its corresponding communication signal, according to the situation of the communication signal, can reflect the current working state of the first antenna 1, especially after it is blocked, compared with the corresponding influence in the open state . In the related technology, no matter how the radiation branch is set in the low-frequency band of the mobile phone, the corresponding radiation pattern is approximately omnidirectional in the direction perpendicular to the metal base plate structure of the mobile phone, and the corresponding radiation zero points exist along the long side of the mobile phone. At both ends; this means that the gain loss of the head-to-hand antenna is relatively large, so that the performance cannot meet the requirements, and the user's experience in surfing the Internet and making calls is poor. The signal processing module 4 can obtain the communication signal of the first antenna 1 in this case, and send the first communication parameter of the communication signal to the main processing module 5, and the main processing module 5 analyzes the first communication parameter for further processing .

The main processing module 5 is used for controlling the second antenna 2 to generate a first coupling signal corresponding to the communication signal of the first antenna 1 according to the communication signal of the first antenna 1 . Specifically, the main processing module 5 can generate an adjustment coefficient corresponding to the first coupled signal of the second antenna 2 according to the first communication parameter of the communication signal, so as to perform communication adjustment on the second antenna 2 . The second antenna 2 is arranged at a corresponding position on the communication terminal, and the first coupling signal generated by it can be superimposed with the communication signal of the first antenna 1 . The result of the superposition can improve the antenna gain, especially the main radiation direction and zero point position of the low-frequency pattern of the antenna, and can reduce the radiation gain towards the direction of the human body, thereby improving the communication quality.

The adjustment coefficient determined by the main processing module 5 is used to control the communication parameter of the first coupling signal sent by the second antenna 2 , that is, the second communication parameter of the first coupling signal. There are two specific adjustment methods for the first coupling signal; one is to adjust the second communication parameter of the first coupling signal accordingly based on the result of the superposition between the first coupling signal and the communication signal. Yes, the communication parameter corresponding to the signal of the superposition result is clarified, and the second communication parameter of the first coupling signal is deduced based on this. This setting method can ensure the accuracy and uniqueness of the result, and this result at least includes reducing The radiation gain toward the direction of the human body; secondly, it is based on improving the communication quality of the communication signal, so that the superposition result at least includes reducing the radiation gain toward the direction of the human body. This adjustment method does not limit the first coupling of the second antenna 2 For the adjustment degree of the signal, the main processing module 5 can set the corresponding adjustment degree according to the specific situation, as long as the radiation gain towards the direction of the human body can be reduced. In addition, the superposition result of the communication signal and the first coupling signal can also increase the radiation gain in the direction away from the human body, which can improve the communication quality while reducing the impact of radiation on the human body.

After the adjustment coefficient is determined, the second communication parameter of the first coupling signal of the second antenna 2 can be directly adjusted, so that the superposition result of the communication signal and the first coupling signal at least includes increasing the radiation gain far away from the shielded direction of the first antenna 1 . The specific content of the first communication parameter and the second communication parameter may include the amplitude and phase of the signal; correspondingly, in order to realize the adjustment of the corresponding parameters of the signal, the adjustment module 6 may specifically include a power divider and a phase shifter, wherein the power divider A shifter is used to adjust the amplitude of a signal, and a phase shifter is used to adjust the phase of a signal. For the second antenna 2, to adjust the first coupling signal generated by it, it is necessary to adjust the amplitude of the first coupling signal through the power divider, and adjust the phase of the first coupling signal through the phase shifter.

In some optional embodiments, in order to ensure the communication quality of the first coupling signal generated by the second antenna 2, the second antenna 2 may be arranged outside the holding area of the communication terminal. The user will hold the communication terminal in the process of using the communication terminal. The first antenna 1 is usually located within the range of the user holding the communication terminal, so within this range, the communication quality of the first antenna 1 will be controlled. lasting impact. In the embodiment of the present disclosure, the second antenna 2 is set up to reduce the influence of the grip on the signal quality. Then, for the good superimposition effect of the communication signal and the first coupling signal, the setting position of the second antenna 2 can avoid the user from using the communication The usual area of the terminal is set outside the holding area of the communication terminal. Generally speaking, the end of the communication terminal is relatively easy to be held by the user, so the second antenna 2 can be arranged at a position close to the middle of the communication terminal, such as at the middle of the back of the communication terminal, so that during use by the user, If the second antenna 2 is not held, the signal quality of the second antenna 2 will be better, and it is easier to compensate for the first antenna 1 .

In some optional embodiments, in order to further improve communication quality, a third antenna may also be included for generating a second coupled signal, and the second coupled signal is used for superimposing the communication signal and the first coupled signal. The function of the third antenna is to perform further superposition with the superposition result of the first antenna 1 and the second antenna 2, and further improve the communication quality of the communication terminal on the basis of the superposition result of the second antenna 2.

The communication terminal provided by the embodiment of the present disclosure is used to send and receive communication signals by setting the first antenna 1; the second antenna 2 is used to generate the first coupling signal, and the first coupling signal is used to superimpose the communication signal; at least one sensor Module 3, configured to detect environmental information within the preset range of the first antenna 1; a signal processing module 4, configured to obtain the first antenna 1 when the detection result of the environmental information includes that the first antenna 1 is at least partially blocked by a human body The communication signal is sent to the main processing module 5; the main processing module 5 is used to control the second antenna 2 to generate a first coupling signal corresponding to the communication signal of the first antenna 1 according to the communication signal of the first antenna 1; and The adjustment module 6 is configured to adjust the first coupling signal of the second antenna 2 so that the result of superimposing the communication signal and the first coupling signal is to reduce the radiation gain towards the direction of the human body. When the first antenna 1 is blocked, the communication signal of the first antenna 1 is compensated by the coupling signal of the second antenna 2 to reduce the radiation gain towards the direction of the human body, thereby improving the situation when the first antenna 1 is held High communication performance, reduce the impact of radiation on the human body, and improve user experience.

Embodiment two

This embodiment provides a signal processing method, please refer to FIG. 3, the method includes: S301, detecting the environment information within the preset range of the first antenna 1 on the terminal; S302, when the detection result of the environment information includes the first antenna 1. Obtain the communication signal of the first antenna 1 when at least part of it is blocked by the human body; S303. According to the communication signal of the first antenna 1, make the second antenna 2 generate a first coupling signal corresponding to the communication signal of the first antenna; and S304 , The communication signal is superimposed on the first coupling signal, so as to reduce the radiation gain towards the direction of the human body.

The terminals in the embodiments of the present disclosure include devices with mobile communication functions such as mobile phones and tablet computers; these devices are usually provided with at least one set of antennas at corresponding positions on the housing for sending and receiving communication signals to achieve wireless communication. As for the installation position of the antenna, taking a mobile phone as an example, the installation method is along the frame of the mobile phone, and is arranged at the bottom and/or top of the mobile phone. Among them, in the embodiment of the present disclosure, the antenna installed on the terminal is the first antenna 1, and the first antenna 1 represents the existing communication antenna of the terminal. Its usual location will be set at the side of the terminal.

In order to compensate the communication of the first antenna 1, mainly to improve the communication quality when the first antenna 1 is blocked and reduce the impact of radiation on the human body, the embodiment of the present disclosure also includes a second antenna 2, the second antenna 2 is also set on the terminal, its function is to generate the first coupling signal, and the purpose of generating the first coupling signal is to superimpose with the communication signal, especially to make the result of the superposition of the two reduce the radiation gain towards the direction of the human body.

In S301, detecting the environmental information within the preset range of the first antenna 1, that is, detecting the occlusion of the first antenna, can usually be realized by a distance sensor, and can be set according to the characteristics of the first antenna 1; for example, if The first antenna 1 is an antenna arranged at the bottom of the terminal, and since the terminal is usually held in use to cover the first antenna 1 with hands, the distance sensors can be arranged on both sides of the terminal; if The first antenna 1 is an antenna arranged on the top of the terminal. Since the terminal is in use by approaching the head to block the first antenna 1, the distance sensor can be arranged on the surface near the side of the user's head. In other words, the purpose of setting the distance sensor in the embodiment of the present disclosure is to detect the occlusion of the first antenna 1 , as long as the first antenna 1 is set at a reasonable position.

In S302, after the occlusion is detected, the first antenna 1 after being occluded and its corresponding communication signal can be further obtained, and the communication signal can reflect the current working state of the first antenna 1, especially after it is occluded , compared to the corresponding effects in the open state. In the related technology, no matter how the radiation branch is set in the low-frequency band of the mobile phone, the corresponding radiation pattern is approximately omnidirectional in the direction perpendicular to the metal base plate structure of the mobile phone, and the corresponding radiation zero points exist along the long side of the mobile phone. At both ends; this means that the head and hands have a large gain loss to the antenna, so that the performance cannot meet the requirements, the user's experience in surfing the Internet and making calls is poor, and the large radiation will affect the human body. At this time, the first communication parameter corresponding to the communication signal of the first antenna after being blocked can be obtained to further analyze the communication condition and provide possibility for subsequent adjustment.

In S303, according to the communication signal of the first antenna 1, the second antenna 2 is made to generate a first coupled signal corresponding to the communication signal of the first antenna, so that the communication adjustment of the second antenna 2 can be implemented. The second antenna 2 is arranged at a corresponding position on the terminal, and the first coupling signal generated by it can be superimposed with the communication signal of the first antenna 1 . The result of the superposition can improve the antenna gain, especially the main radiation direction and zero point position of the low-frequency pattern of the antenna, which can play a very good role in changing the radiation gain towards the direction of the human body, thereby improving the communication quality, and Reduce the impact of radiation on the human body.

There are two specific adjustment methods for the first coupling signal; one is to adjust the second communication parameter of the first coupling signal accordingly based on the superposition result between the first coupling signal and the communication signal, and its specific meaning is , the communication parameter corresponding to the signal of the superposition result is clarified, and the second communication parameter of the first coupling signal is deduced based on this. This setting method can ensure the accuracy and uniqueness of the result, and this result at least includes reducing the orientation The radiation gain in the direction of the human body; the second is to improve the communication quality of the communication signal, so that the superposition result at least includes reducing the radiation gain in the direction of the human body. This adjustment method does not limit the first coupling signal of the second antenna 2 The degree of adjustment can be set according to the specific situation, as long as the radiation gain towards the direction of the human body can be reduced.

In some optional embodiments, according to the communication signal of the first antenna 1, causing the second antenna 2 to generate the first coupled signal corresponding to the communication signal of the first antenna includes: judging the communication signal according to the first communication parameter of the communication signal Whether the transmission power of the communication signal meets the preset requirement; if it is determined that the transmission power of the communication signal does not meet the preset requirement, then according to the first communication parameter, an adjustment coefficient corresponding to the first coupling signal of the second antenna is generated; and the first coupling signal is generated, And adjust the second communication parameter of the first coupling signal according to the adjustment coefficient. The fact that the first antenna 1 on the terminal is blocked does not mean that it will inevitably lead to deterioration of communication conditions. For example, if the terminal is blocked by the user's hand, the communication quality of the first antenna 1 will be significantly reduced, and the radiation of the terminal will also affect the human body; Put it in your pocket, so in fact, this kind of occlusion will have little impact on the signal quality, and its radiation will not have much impact on the human body. Therefore, before the adjustment, it is possible to determine whether the transmit power TRP (Total Radiated Power) of the first antenna 1 meets the preset requirements according to the first communication parameters of the communication signal of the first antenna 1 at this time; Just make adjustments and keep the current state; if the preset requirements are not met, then the second antenna 2 is used to make compensation, thereby improving the signal quality.

In S304, the communication signal is superimposed on the first coupling signal, so as to reduce the radiation gain toward the direction of the human body. The specific content of the first communication parameter and the second communication parameter may include the amplitude and phase of the signal; correspondingly, in order to realize the adjustment of the corresponding parameters of the signal, it may specifically include a power divider and a phase shifter, wherein the power divider is used to adjust The amplitude of the signal, and the phase shifter is used to adjust the phase of the signal; for the second antenna 2, to adjust the first coupled signal generated by it, it is necessary to adjust the amplitude of the first coupled signal through the power divider, and adjusting the phase of the first coupling signal by using the phase shifter.

In some optional embodiments, before detecting the occlusion around the first antenna 1 on the terminal, it may further include: determining that the first antenna 1 is in a preset communication state. Although the core function of the terminal is communication, most of the time the user is not using the terminal for talking; therefore, in many cases, it is not necessary to improve the signal quality of the first antenna 1 of the terminal . For this situation, the corresponding preset communication status of the first antenna 1 can be set. For example, the preset communication status can be a call, a large traffic usage data network, etc., and only in these preset communication statuses can the follow-up Operations such as detecting the blocking condition of the first antenna 1 can reduce the waste of system resources.

In some optional embodiments, the first communication parameter may specifically include at least one of the following: the amplitude of the communication signal, and the phase of the communication signal. That is to say, the type of the communication parameter may include amplitude and phase, and when adjusting the first coupling signal of the second antenna 2 , the amplitude and phase are correspondingly adjusted.

In some optional embodiments, it may further include: the communication signal is superimposed on the first coupled signal, so as to increase the radiation gain in a direction away from the human body. In addition to reducing the radiation gain toward the human body, it can also increase the radiation gain away from the human body. While reducing the impact of radiation on the human body, the signal quality is improved in all directions.

Adjust the amplitude and phase of the coupling signal to change the amplitude ratio and phase difference between the first coupling signal and the communication signal, so as to reduce the impact of the direction of the human body (ie, the direction of the user's hand, or the direction of the user's head occlusion). Radiation gain, improve the purpose of other azimuth radiation gain.Concrete, with reference to shown in Figure 5, when adjusting, the power classifier feeds into the second antenna 2 with the signal of the first antenna 1 equal amplitude, and the phase shifter gives the second antenna 2 Antenna 2 feeds a signal that is ahead of the first antenna 1 in phase θ to form the first coupled signal of the second antenna 2. The communication signals corresponding to the first antenna 1 and the second antenna 2 and the first coupled signal are superimposed in the near field, The amplitude of composite signal strengthens, and gain increases, and the phase of composite signal is φ=arcsin(θ/kd), and d is the spacing between the first antenna 1 and the second antenna 2 in this formula, and k is wave number, and k= 2=number, and λ is wavelength. The first coupling signal that the second antenna 2 feeds in and the communication signal of the first antenna 1 carry out near-field superposition, make the signal energy of human body head-hand position reduce,

The signal energy of angle and azimuth is increased, improving head-hand efficiency. After the superposition of coupled signals, the antenna gain loss is reduced and the communication quality is improved.

In some optional embodiments, after the communication signal is superimposed with the first coupling signal to reduce the radiation gain toward the human body, it may further include: determining whether the preset communication is satisfied according to the result of the superposition of the communication signal and the first coupling signal. Requirement; if not, make the third antenna generate a second coupling signal, and the second coupling signal performs positive gain on the superposition result of the communication signal and the first coupling signal. The function of the third antenna is that it can be further superimposed with the superposition results of the first antenna 1 and the second antenna 2, and further improve the communication quality of the terminal on the basis of the superposition of the second antenna 2; the so-called communication signal and The superposition result of the first coupled signal is positively gained, which means that the second coupled signal generated by the third antenna will further affect the coupling of the first coupled signal to the communication signal from the positive direction, that is, to further reduce the coupling towards the human body. direction, and/or further enhance the radiation gain in directions away from the human body.

The signal processing method provided in this embodiment detects the environmental information within the preset range of the first antenna 1 on the terminal; when the detection result of the environmental information includes that the first antenna 1 is at least partially blocked by a human body, obtain the information of the first antenna 1 Communication signal; according to the communication signal of the first antenna 1, the second antenna 2 generates the first coupling signal corresponding to the communication signal of the first antenna 1; the communication signal and the first coupling signal are superimposed to reduce the radiation towards the direction of the human body Gain, in some implementations, when the first antenna 1 is blocked, the communication signal of the first antenna 1 is compensated with the coupling signal of the second antenna 2, so as to reduce the radiation gain toward the direction of the human body, thereby improving The communication performance when the first antenna 1 is held can reduce the impact of radiation on the human body and improve user experience.
